Anti Oxidant Additive

Protecting Polymer as we care for Nature

PLAST ANTIOXIDANT MB 051& 052 PE are used to protect polymers from degradation, both during processing(short term stabilization) and during use (long term stabilization). Polymer degradation generally results in gel formation,changing melt flow index, loss of mechanical properties,aesthetics(crazing, gloss reduction, chalking) and discoloration due to heat during polymer processing , sun light & oxygen present in the environment . This process releases free radicals causing polymer chain scission or breakage which is prevented by Antioxidants as “Free radical Scavangers”.

Preventing Auto Degradation

Antioxidants are based on Butylated Hydroxy Toluene chemically known as 2,6 di-tert- butyl- p- cresol which is commonly used in Polyolefins and they do inhibit auto oxidation that occurs when polymers reacts with atmospheric oxygen.
>Aerobic degradation occurs gradually at room temperature, but almost all polymers are at risk of thermal-oxidation when they are processed at high temperatures, light assisted oxidation & exposed to UV light.

How it Works?

Generally, thermal degradation is caused in polymers under thermo -mechanical or thermo- oxidative conditions. Heat during polymer processing and end use environment produces free radicals which cause polymer chain scission or breakage leading to loss of mechanical properties.
read more Polypropylene (PP) and polyethylene (PE) resins are inherently unstable and degrade when exposed to oxygen. When PP or PE degrades, chain scission, or the breaking up of the polymer chains into smaller pieces, takes place. The physical properties of the polymer deteriorate and its average molecular weight (chain length) decreases, melt flow rate increases and a powdery surface eventually forms. Polymer degradation generally happens during oxidation process, resin producers seek to stabilize the phenomenon by adding stabilizers such as antioxidants. The degradation of these polyolefin resins follows a cyclic oxidation process which involves initiation, propagation and termination respectively.

Types of Anti oxidants

Primary AO
They are free-radical scavengers or sometimes called as radical chain terminators consisting of hindered phenol and amine derivatives; generally, the higher the molecular weight of the additive, the better the performance.
Secondary AO
They are peroxide scavengers are often called secondary antioxidants or hydroperoxide decomposers . They are often used in combination with free radical scavengers (primary antioxidants) to achieve a synergistic inhibition effect.
Thioesters
They are organic sulphides containing sulphur which are very effective hydrogen peroxide decomposers during long-term thermal aging and are often used in combination with primary antioxidants that provide good protection during processing, like hindered phenols. Primary antioxidants and thioesters are added to the polymer to provide stability while secondary antioxidants are added to provide colour and processing stability.

Types of Anti oxidants

PRP Pipe

They have significant role in PPR pipes and fittings used in the Infrastructure sector needs as the chances of degradation is predominant in the presence of UV Light.

HDPE Pipe

More specifically, AO increases Oxidation Induction Time in a DSC to measure the level of thermal stabilization for HDPE pipes.

PE Film

PE films used for variety of applications such as Agriculture, Construction,Food packaging, etc requires AO to retain it’s polymer structure & prevent degradation at the end user.

Water Tank

Preventing yellowing of plastics during processing, especially in Water Tanks.

Recycling Material

AO acts as a “top up reservoir” in addition to those added at resin producer level by protecting Polymer when subjected to multiple heat sequences in re-processing & re-cycling. Also it helps incorporation of Post Industrial & Post Consumer Recycled material content in virgin polymers for meeting sustainability & to meet economic objectives.
